ANAHEIM, CALIF. - Ad-vanced Composites Group Inc. of Tulsa, Okla., supplied epoxy prepreg and film adhesive for the fuselage of the unmanned aerial vehicle Tier III Minus, which was scheduled for its initial launch in early April. ``Our system can make aircraft applications affordable,'' John Powers, market development manager, said in an interview at the firm's SAMPE exhibit in Anaheim.
The Advanced Research Projects Agency contributed to development of the high-altitude-endurance UAV. Lockheed Martin Corp.'s Skunk Works is the prime contractor.
Two plies of the toughened epoxy, resin-impregnated carbon fabric form sandwich face sheets of the forebody's upper shell, and the film adhesive bonds the face sheets to Nomex honeycomb core. The shell cures on a urethane foam tool at about 160§ F and post-cures free standing at 250§ F.
Separately, the group introduced three rapid-cure prepreg materials for recreational products.
Two cure at 230§ F and the other at 250§ F, each in 10 minutes.
Advanced Composites Group Inc. is the U.S. subsidiary of Advanced Com-posites Group Ltd. in Heanor, England.
U.S. operations employ 25 among a company total of 165, and recorded 1995 sales of $7 million, out of a coporatewide total of $24 million.
